Abstract

The utility model discloses a sand box cover and body connecting structure, which comprises a box body and a box cover, wherein two vertical lugs are arranged on the upper outer surface of the box body; a shaft pin is placed in holes of the two vertical lugs; a large-diameter step body is arranged at one end of the shaft pin, and a hole matched with a cotter pin is formed in the other end of the shaft pin; the lower end of a rocker shaft is provided with a sphere; the left and right sides of the sphere are planes, and the sphere is placed between the two lugs and is provided with a hole matched with the shaft pin in a rotating manner; notches matched with the rocker shaft are formed in a convex plate at a box body port and a convex plate at a box cover port; a thread matched with a nut is formed at the upper end of the rocker shaft, and a handle is fixed on the rocker shaft below a thread body; and the lower surface of the end, fixedly connected with the rocker shaft, of the handle is an inclined plane, and the plane is matched with an upper inclined plane of a pressing plate on the convex plate fixed on the box cover port. Compared with the prior art, the sand box cover and body connecting structure has the remarkable advantages of high efficiency, small labor intensity and high safety and reliability.

Description

The syndeton of a kind of sandbox case lid and casing

Technical field:

The utility model relates to a kind of casting sandbox, particularly the syndeton of a kind of sandbox case lid and casing.

Background technology:

Foundry goods is blank commonly used in machinery, consumption is very large, and foundry goods is in casting cycle, because weight and its coefficient of expansion of molten iron are larger, can cause case lid by jack-up, the lighter's casting deformation and scrapping, the overflow of severe one molten iron is accidents caused, for avoiding moving the defects that causes on case lid, existing measure is to place weight on case lid, and weight leans on workman's experience, and the shortcoming of this scheme is that labour intensity is large, efficient is low and reliability is relatively poor.

Summary of the invention:

The purpose of this utility model is to provide a kind of labour intensity is low, efficient is high and safe and reliable a kind of sandbox case lid and the syndeton of casing.

the technical scheme that realizes the utility model purpose is, the syndeton of a kind of sandbox case lid and casing, comprise casing and case lid, it is characterized in that: be provided with two vertical otic placodes on the outer surface on casing top, bearing pin is placed in this two lug plate holes, one end of this bearing pin is large diameter step body, the other end is provided with the hole of joining with split pin, the swinging shaft lower end is spherical, the left side of this spherical, right both sides are the plane, this spherical is placed between above-mentioned two otic placodes, this spherical is provided with bearing pin and turns mutually the hole of joining, the outer flange of casing port and the outer flange of case lid port are provided with the breach that matches with swinging shaft, the upper end of swinging shaft is provided with the screw thread that matches with nut, be fixed with handle on the swinging shaft below threaded body, this handle is the inclined-plane with the lower surface of the termination that swinging shaft is connected mutually, this inclined-plane matches with the ramp that is fixed on the pressing plate on the outer flange of case lid port.

The utility model has the remarkable advantage that efficient is high, labour intensity is little and safe and reliable compared with the prior art.

Description of drawings:

Fig. 1 is perspective view of the present utility model; Fig. 2 is the swinging shaft structural representation that case lid and casing tighten up state.

The specific embodiment:

the utility model for the technical scheme of the defective that the solution prior art exists is, be provided with two vertical otic placodes 10 on surface outside sandbox casing 1 upper port below flange, swinging shaft 3 lower ends are ball, the left side of ball, right both sides are the plane, this ball is transferred between above-mentioned two otic placodes, bearing pin 5 is placed in this two otic placode and waves axis hole, one end of this bearing pin is large diameter step body, the other end is provided with the hole that matches with split pin, breach on the outer flange 4 of the outer flange of swinging shaft and casing port and case lid 2 lower port matches, the screw thread of the upper end of swinging shaft and nut 8 match, be fixed with handle 9 on the swinging shaft below this nut, this handle and swinging shaft are connected mutually, and to be inclined-plane 7 match with the inclined-plane of the upper surface that is fixed on the pressing plate 6 on the outer flange 4 of case lid lower port for the lower surface of part.

Method of operating of the present utility model, by the position of adjustment nut on swinging shaft, swinging shaft can be entered in the outer flange breach of casing and case lid, when molten iron injects die cavity, the rotation of hand-held handle right-to-left, effect by the inclined-plane moves down case lid, and case lid and casing are compressed, and when getting foundry goods, reverse rotation handle, case lid and casing unclamp, swinging shaft just can be thrown off case lid port row flange breach, removes case lid, can take out foundry goods, this structure operation is both convenient and swift, and efficient is high and safe and reliable.

Claims

1. the syndeton of a sandbox case lid and casing, comprise casing and case lid, it is characterized in that: be provided with two vertical otic placodes on the outer surface on casing top, bearing pin is placed in this two lug plate holes, one end of this bearing pin is large diameter step body, the other end is provided with the hole of joining with split pin, the swinging shaft lower end is spherical, the left side of this spherical, right both sides are the plane, this spherical is placed between above-mentioned two otic placodes, this spherical is provided with bearing pin and turns mutually the hole of joining, the outer flange of casing port and the outer flange of case lid port are provided with the breach that matches with swinging shaft, the upper end of swinging shaft is provided with the screw thread that matches with nut, be fixed with handle on the swinging shaft below threaded body, this handle is the inclined-plane with the lower surface of the termination that swinging shaft is connected mutually, this inclined-plane matches with the ramp that is fixed on the pressing plate on the outer flange of case lid port.
